2. What separates humans from animals and angels according to Kant?
What does Kant mean by the good will?
What does he mean when he says good will is the only thing that is ‘good without qualification’?
What does it mean to act according to a good will?

3. Lesson Objectives To understand what Kant means by duty.
To differentiate acting out of duty and acting in accordance with duty.
To distinguish between categorical and hypothetical imperatives.

4. Doing Your Duty
A man is drowning in a river. You could walk on by or you could help. You decide to help, but what is motivating you?
You want to help because you think he is a rich and will give you a reward.
You want to help because you will receive praise (and maybe some attention from the press).
You want to help because you recognise that he might die and that he should be saved if possible.
Which motivation according to Kant is the only one that has moral worth? Why?

5. Which of these things do you think counts as a duty?
To preserve someone elses life, even though I find it unbearable?
To commit suicide when I find life unbearable?
To keep my promise, even though my friend will suffer as a result?
To steal the bread because my children are starving?
To punish my child because I enjoy it?
To take care of my parents because they took care of me?
To take care of my old parents, even though they didn’t take care of me?
As a parent to send my child to a good school?
As a motorist to obey traffic lights?
As a Nazi to kill Jews?

6. Problem – Is a good will always good?
Read the criticism on page 259 – is the author right?
What do you think Kant would say?

7. Defining Duty
For the moment then we can identify duty (and therefore the good will) according to Kant as:
Doing the right thing for the sake of doing the right thing with no ulterior motivation.

8. Kant’s view of Human Nature
Another reason why motive is important to Kant is his view that we are imperfectly rational beings.
Animals Human Beings God / Angels
Desires
Inclinations
Desires & Reason
Reason
Animals follow their desires
and inclinations only. They
have no reason, so behave
according to the empirical
laws of cause and effect,
led by their appetite
and instincts.
God and angels are perfectly rational beings,
without appetites and desires to lead them astray from
following reason and
objective moral laws.
Human nature experiences
the tension of desires and inclinations (their animal self) versus the voice of reason (their God-like self).
Acting from our desires means we’re acting out of self-interest and that makes us no better than animals. We should be looking to our reason to guide us, not our base instincts.

9. Accordance with Duty Vs Acting Out of Duty
Kant emphasises that we must not be motivated out of self-interest, or even out of love or sympathy for others, because emotions and inclinations can be variable, love can be selfish and sympathy narrowly focused or dependent on circumstances.
An action is only morally good if the motivation behind it is to do your duty. This is different from simply acting in accordance with our duty. According to Kant, an act which is performed because you want to do it (for some emotional or physical reward) may be the right thing to do, but it is not a morally praiseworthy act. An act is only morally good if the motivation behind it was to fulfil your moral duty, regardless of your personal preferences.
Can you think of any issues people might have with this view of morality?

10. Out of Duty Vs Accordance
A man is drowning in a river. You could walk on by or you could help. You decide to help, but what is motivating you?
You want to help because you think he is a rich and will give you a reward.
You want to help because you will receive praise (and maybe some attention from the press).
You want to help because you recognise that he might die and that he should be saved if possible.
What is the key difference between the three that makes C the only morally praiseworthy act?

11. Problem – Duty as morality
Who would you say is more moral?
Jasmin, who donates to charity begrudgingly because she knows it is her duty to help people who are less fortunate than herself.
Damien who donates to charity because he wants to help other people and it makes him happy to think people might use his money better than him.
According to Kant someone who, through the use of dispassionate reason, recognises her duty to help others in distress even though she doesn’t particularly care for other humans is more praiseworthy than someone who would have helped duty or not.
Jasmin in this particular case, must act against her natural desires and inclinations.
Meanwhile, Damien is led purely by his slavish emotions.
Therefore, according to Kant, Jasmin is more morally praiseworthy.

12. Problem – Duty as morality
Read the activity on page 261 and explain on your whiteboards the issue it highlights with Kant’s theory.

13. But what is our duty?
As we’ve said so far, our duty is to do the right thing for the sake of doing the right thing. We can work out what the right thing is by using our reason (something all humans have and sets us apart from animals) to identify clear moral laws. Our task for the rest of this discussion is to identify what moral laws reasonable, rational beings would come up with.

14. Tasks – Whiteboard First!
What does Kant mean by duty? Why do humans need this whilst animals and God don’t?
What is the difference between acting in accordance with duty and acting out of duty?
Why does Kant think the idea of moral duties and laws should apply to all humans?

15. A Quick Summary So Far…
Having good intentions (good will) is good in itself, regardless of what it achieves.
To have a good will is to be motivated by duty.
Being motivated by duty means doing what is right, regardless of desires / emotions.
Being motivated by duty therefore means being motivated by reason, rather than desires or instincts. This is something humans can do.
Even if our desires or instincts coincide with our duty (accordance) it’s still not morally praiseworthy to act on them. It’s only moral if we act purely out of reason / duty.
Reason is universal; the same for everyone.
Moral duties are universal; the same for everyone.
Reason should therefore be used determine what our moral duties are.

16. What does a moral law look like?
Like scientific laws they should be objective (since being subjective would mean they are subject to peoples desires and concerned with consequences in individual situations).
They should also be universal (since all humans have the capacity to reason and therefore do their duty).
From this we can conclude that moral laws should be general rules that outline how we should act that we can then apply to specific circumstances.
Putting all this together Kant comes up with…

17. The Categorical Imperative
The Categorical Imperative is a way of deciding whether my possible actions are morally good or bad. By using it I can form moral rules / imperatives that dictate how I should act.
In calling these moral imperatives ‘categorical’, Kant contrasts them with hypothetical imperatives (more about this in a moment).
Hypothetical imperatives are called ‘hypothetical’, because they are always conditional on our own individual self-interest or desires. (Bad!!!)
Categorical Imperatives, on the other hand, are not concerned with our desires.
They are straightforward commands which enable us to fulfil our duty.
The Categorical Imperative
1.) “Act only on that maxim through which you can at the same time will that it should become a universal law.”
2.) “Act in such a way that you always treat humanity, whether in your own person or in the person of any other, never simply as a means, but always at the same time as an end.”

18. Categorical Vs Hypothetical
Categorical = Unconditional commands binding on everyone at all times, based on reason, not feelings. Categorical imperative: ‘you ought to tell the truth’ (Kant called these maxims, or general rules). Hypothetical imperative: If -> Then statements. “If” you want A “Then” do B. Subjective, depending on whether you have a particular goal or feeling. Hypothetical imperative: ‘if you are bothered about hurting people, then you shouldn’t lie’

19. Categorical or hypothetical?
Be nice to your granny so she will leave you money in her will.
Preserve life.
I should do more sit ups, I want some more muscle.
I should look after my sister.
Tell the truth so people will trust you.
I shouldn’t steal as much as I do.
NB Hypotheticals don’t always have an “if”!!!
Whiteboards – 2 Categorical imperatives, 2 Hypothetical imperatives – Big enough for me to see from the front!

20. The Categorical Imperative
Categorical Imperatives are categorical because their function is not to advise us how to satisfy our self-interest or desires; instead, they command us how to act irrespective of our interests or desires.
The Categorical Imperative is therefore absolute; it is absolutely binding on us, irrespective of our desires or our situation.
Kant famously presents different versions or formulations of the Categorical Imperative. Although he considers them all to be part of the same moral law.
The first two are absolutely central to his ethical theory, and it’s imperative that you know these inside out.
The Categorical Imperative
1.) “Act only on that maxim through which you can at the same time will that it should become a universal law.”
2.) “Act in such a way that you always treat humanity, whether in your own person or in the person of any other, never simply as a means, but always at the same time as an end.”

21. 1. Formula of Nature - Universalisability
‘Act as if the maxim of your action were to become through your will a universal law.’
Whilst hypothetical imperatives are based on desires and ‘ends’. Categorical imperatives are not, as desires are not universal.
Stripped of desires and ‘ends’ we can only base our categorical imperative on the idea of reason and rationality itself.
It is imperative that I act in a way that is consistent with rationality, in other words a way all rational beings could act.
Since all humans are rational beings, it makes sense to say that I should only act according to principles that we could all follow.
Thus I should only act according to principles that could be universalised.

22. Can you think of 2 actions that can be universalised and 2 that can’t?
Formula of Nature - Universalisability
‘Act as if the maxim of your action were to become through your will a universal law.’
In order to pinpoint whether a maxim has moral worth, and truly springs from the ‘good will’, we have to ask ourselves the following question: Would you like other people, who find themselves in the same situation as you, to always act in the same way?
If not, you are involved in a contradiction and what you are thinking of doing goes against reason and the good will. This is immoral, because it goes against our nature as rational human beings.
Can you think of 2 actions that can be universalised and 2 that can’t?

23. Formula of Nature - Universalisability
‘Act as if the maxim of your action were to become through your will a universal law.’
Take, for example, promise keeping. If you decide that you’re going to break a promise, then that clearly involves you in a contradiction.
Imagine if everyone else acted the same way. We’d then have a world in which no promises were kept. That’s clearly a contradiction, since a promise, by definition, is something you keep, so if we had a world in which no promises were kept, we’d have a world without promises.

24. Formula of Nature - Universalisability
‘Act as if the maxim of your action were to become through your will a universal law.’
For Kant there are two possible reasons a law could not be universalised:
Contradictions of the laws of nature / conception’ – these cannot be universalised as they are self contradictory. For example, ‘everyone should make false promises’ – impossible since promises require that someone would believe you, and if everyone made false promises, no one would believe anyone.
Contradictions in the will’ – these are not contradictory in themselves, but no one could wish to see them universalized. For example ‘don’t help others in need’ – something we all need at some point in our lives, so would not wish to see universalised.

25. Complete the task on page 82 of the textbook.
The Four Step Program!
When it comes to applying Kant’s first categorical imperative then, there are four steps we should take:
Step 1: Work out the underlying maxim. A maxim is a general rule governing our actions. Remember it should be as general as possible.
Step 2: Can you conceive of a world where this is the law for everyone? (i.e. can it be universalised without contradiction?)
Step 3: Can you rationally will that this be a universal moral law? (i.e. would it make sense for people to rationally want this?)
Step 4: If the answer to all the above questions is yes – the action can be said to be morally permissible.

28. “Act as you wish, even if it impedes on someone else's autonomy.”
Second Formulation
Think back to Kant’s law of universalisability we discussed last lesson, couple this with Kant’s belief that all humans are rational and therefore valuable. Would it be possible to universalise the following maxim?
“Act as you wish, even if it impedes on someone else's autonomy.”
If not, why not?

29. Formula of Humanity
‘Act in such as way as you always treat humanity whether in your own person or on the person of any other, never simply as a means, but always at the same time as an end’
With this formulation of the Categorical Imperative, Kant hits on one of the fundamental principles of morality. We must never treat other human beings as means to an end, but as with worth in themselves.
In other words, we mustn’t ever treat others instrumentally, or use them, but treat them with the full respect that their humanity deserves.
How did Kant reach this? He sees it as a universal self-evident principle (a priori). It begins with a person observing that one is a rational and free agent and moves to seeing other people in a similar light. Once you recognise this, you realise people in general have intrinsic worth and should not be abused.

30. Let’s look at some examples…
Formula of Humanity
‘Act in such as way as you always treat humanity whether in your own person or on the person of any other, never simply as a means, but always at the same time as an end’
It’s important to note here that Kant thinks that this formulation has exactly the same meaning (and the same results) as the universal law formulation. He just thinks it presents the idea in a way that is more intuitive.
Let’s look at some examples…

31. Formula of Humanity How does this make you feel?
‘Act in such as way as you always treat humanity whether in your own person or on the person of any other, never simply as a means, but always at the same time as an end’
You acquire a new friend, Sam. Sam goes out of her way to be nice to you, pays you compliments, lets you borrow her fancy camera and even buys you a thoughtful birthday present. However, you find out in reality Sam doesn’t like you at all. She only became friends with you in order to meet your cousin who is an up and coming journalist. Sam thinks your journalist cousin could help make her famous.
How does this make you feel?
Was Sam’s behavior wrong? Why?
How does Kant express this?

32. Formula of Humanity
‘Act in such as way as you always treat humanity whether in your own person or on the person of any other, never simply as a means, but always at the same time as an end’
Which of the following treats people as “ends” not “means”?
Aborting a foetus.
Paying a plumber to mend your sink.
Blowing up yourself to further a terrorist cause.
Abolishing slavery.
Paying for something with fake £20 notes.
IVF.
Your plain has crashed; in order to survive you resort to cannibalism.

33. Formula of Humanity Go through the situations on page 82 again.
‘Act in such as way as you always treat humanity whether in your own person or on the person of any other, never simply as a means, but always at the same time as an end’
Since this version of the categorical imperative is allegedly the same as the first formulation, we would expect the same results in the situations we looked at last lesson:
Go through the situations on page 82 again.
For each one ask if the act involved is treating people merely as a means to an end, or as an end in themselves.
Decide based on this whether or not the action would be judged right according to Kant’s second formulation.

34. The Categorical Imperative
Categorical imperatives are categorical because their function is not to advise us how to satisfy our self-interest or desires; instead, they command us how to act irrespective of our interests or desires.
The categorical imperative is therefore absolute; it is absolutely binding on us, irrespective of our desires or our situation.
Kant famously presents three versions or formulations of the categorical imperative. Although he considers them all to be part of the same moral law. It is these formulations that allow us to work out our duty in any situation.
The first two are absolutely central to his ethical theory, and it’s imperative that you know these inside out.
The Categorical Imperative
1.) “Act only on that maxim through which you can at the same time will that it should become a universal law.”
2.) “Act in such a way that you always treat humanity, whether in your own person or in the person of any other, never simply as a means, but always at the same time as an end.”

35. So what have we covered?...
Having good intentions (good will) is good in itself, regardless of what it achieves.
To have a good will is to be motivated by duty.
Being motivated by duty means doing what is right, regardless of desires / emotions. Following your reason.
Since reason is universal, it makes sense that we should only do things that all beings could rationally do / want (first formulation).
Since all beings are rational, it would also make sense for us to not use them in a way that violates their inherent value. This also couldn’t be universalised.
Therefore, rational beings should only be treated as an end in themselves, not merely as a means to an end (second formulation).

36. Tasks – Whiteboard First!
What is Kant’s second formulation of the categorical imperative?
What does Kant think about humanity that leads to this formulation?
Give an example of a maxim (remember a general law!) that would not involve treating a person as a means to an end.
Give an example of a maxim that would involve treating a person as a means to an end rather than an end in themselves.
Do you think this is a more intuitive version of the categorical imperative than the first formulation?

39. Kant and Human Rights
Kant’s focus on autonomy and the inherent value of all humans in ethics has been extremely influential. The development of human rights is closely linked to these concepts and many of Kant’s arguments have been used to support these ideals.
Slavery, false imprisonment, torture, and so on are all ways of treating people as a means to some other end and therefore undermine their autonomy.
The basis of all human rights is to enable individual, rational autonomy, and Kant’s philosophy played a significant part in their development.
